VRay not working


Installed a new memory stick this afternoon and now V-Ray beta isn’t working. I installed the newest beta. I get the tool bar. I can drag materials from the Express tool bar to geometry and I can open the Asset Editor

But when I click Render nothing happens.

The network server icon on my taskbar says it’s running.

Any thoughts on where to trouble shoot this? I need a render for tomorrow morning.

Thanks for any ideas you have
